The present invention relates to improvements in busor car window construction; and more particularly to the vertical side'channels within- MI which the window sash supported-at-its vertical "E edges and adapted to be raised and lowered. ,Cer-

tain typesof side channels heretofore known consist of a stop member, usually the outside 'stop, whichis fixed to the window frame creasing, and

which includesa leg portion and abase portion,

1 and aremovable stop, usually the inside stop, which isconnected; to the outside stop to form the opposed leg of the channel. The inside stop ineludes a rack with which the sash lock is adapted to cooperate, this rack being disposed in exposed 1'5 relationin a plane inwardly'of thecentral plane of the window sash. It is an object'of the present invention to provide a side channel-which willdbe compact, narrow in width, and in which theremovable stop may be conveniently engaged-and 20- disengaged with the fixed stop, and further to provide means iorisecuri'ng a removable stop to the fixed stop whichwill not material-lyincrease the width of the channel. A further object is to provide a side channel in which the-rack'means' 25,; for the'sash lock may be conveniently housed therein in concealed relation substantiallyin the central verticalplane-of the window sash, and

accommodate these parts.

without I increase in the 'width of the channel to 33:: With the above and other objects in View an embodiment of the invention isshdwn in the accompanying drawing andthisem-bodiment will be hereinafter more fully described with reference thereto, and the invention" will be finally'pointed sellout-in the claim.

Similar reference characters indicate corre sponding parts throughout the several-rfigures-of I I Referring to the drawing, the window sash; with which the side channel, according to my .invention is incorporated, comprises a glass I, having:

- a top rail (not shown) a. bottom mill, and? a pairof vertical side straps '3, connecting the top. :and r5 bottom rails, only onebftheseside straps'beingshown. a l The side. strap is of U -shape channel form in cross section to'receive the'vertical edge of the" glass, its vertical edgesbeing bent outwardly and 2i);

rearwardly, as at. '4"4,to engage the'edge' of the U-shape-piece of facing materialiwhich is cemerited, riveted, or-otherwise suitably secured about the side strap, thismaterial being ofr-suitable composition, similar to felt or leather, as're-1 gards its: wearing and. sealing, qualities, andadapted to haveeasy sliding engagement inther side'post channel; A sash lock plunger 51is' dis-.I' posedin the bottom rail'in a suitable channel and 'isadapted to be projected by'spr-mg pressure; and" at): I

to be manually retracted by an operating handler in the usual manner. 'I'he'plunger projects at' its 1 nose and through'slots' l and flirespectively m; vided in the side strap 3' and facing material 5,

and-is adapte'dto engage therack disposed with in'the side channel, as willhereina'fter more fully appear. 7 I I I The side channel according tojmy inventionis of generally U-shape' in cross-sectionand com prises a fix'edistop, usuallyat the outside, of right 49: I angulariorm in cross section, having afiange' 9'- con'stituting one leg of. the channel, a transversely disposed" base lflinteg'rally connected to theflange 9 in' spaced relation to the side post engaging foot of the flange and extending forthei majorportion of its Width'in parallel relation to the surface of the side'post and being stepped at; its end, as at; I I, to" engage the post. A relatively narrowfiange' I2 is formed' 'upon the step portion J I'in spaced relation to the'rise' I3'of thestepped portion, agr'oove [4" being formed between said" flange IZ'andthe'rise I3; The flange l2 isin-'- wardly spacedfrom the extremity of the stepped portion II to form a seating shoulder I5 for en- I gagement'by the removable stop, aswill presentf The flange I2 is provided at suitable intervals along the height of the channel with notches 20, only one of which is shown, eachhaving ra slot. 2 l

in its lower end, the outer face of which is downwardly and rearwardly inclined, and which notches and slots are adapted to'be engaged by a series of cross pins 22 connected and secured between the leg IT and the flange I8 of the removable stop. The removable stop is adapted to be first pressed into engagement with the flange l2 withthepins 22, engaged in the notches 21], and then longitudinally moved downwardly sothat the cross pins 22 enter the slots 2] witha wedging action thereby drawing the removable stop,tight-; 1y against the flxed stop. When attaching the removable stop the innerend of the leg ll may be rolled over the protrusion 16 atthe end of the flange 12 into the groove M, the flange i8 seating upon the seatingshoulder {5 at, theouter side of, the flange i2. When the removable stop is in this position it will be noted that the pressure of the felt. material 5 is outwardly upon the outer end of the leg ll. pressing theinner end of the leg against the rise It about the protrusion it as a fulcrum, thestop. being thus retained snugly in position by the pressure of the. felt material, and in turn retaim'ng the felt material in place. The removable stop ;may thus be very readily and conveniently engagedwith the fixed stop, and thereuponlongitudinally moved into locked position.

The flange I2 is provided at its lower end with a locking screw 23 extending through a hole 25 in the flange and screwed into a block member; 25.disposed at the inner side of theflange The.

loweraend of the leg portion 16 of the removable stop is provided with a cut-out 26 which engages abouttheblock member 25 in the assembled rela-;

tion of the stops and the flange, i8 is provided a itslower .end with an open-ended slot 2T which engagesover theshank of the locking screw 23 as the outside stop is moved downwardly to its assembled position. Thereupon the screw 23 is tightened, drawing theblock member 25. tightly against the inner side of the flange l2 and the .head of. the screw tightly against theflange 18 of the removable stop, thereby securing the latter against retractive or disengaging movement.

. ,A channel strip 2.8 is disposed within the side channel, and. has its forward edges bent inwardly as at 2929 to engage ,thefacing material 5, these edges being spaced apart to, provide a vertical slot through whichthe sash lockgplunger 6 projects and is adapted to have vertical m0ve-- ment as the window is raised and lowered. A pressure spring is secured to the rear side of the channel strip, and comprises a right angularbase portion 38, spot-welded, or otherwise suitably secured to the rear face and one side face of the channel strip, an intermediate spring leafportion 3| bent from one vertical edge of said base por tion, and a spring leaf abutment portion 32 bent back from the edgeof the spring leaf portion 3|,

- in thcjappended claim.

this spring leaf portion 32 preferably having a convex engaging surface 33 for engaging the base of the side channel. In the assembled relation this spring is compressed between the base In of. the side channel and the base of the channel strip 28, and presses the latter inwardly against the facing material 5 to yieldingly retain the edge or the window sash against looseness and rattlin and at the same time permit it to be easily raised and lowered. A rack member is secured to the I inner face of the channel member, as by spotwelding, riveting, or other suitable means, and is adapted to be engaged by the sash look plunger 6 to retain the window sash in any desired point of adjustment. This rack member is in substantially' concealed relation in the central vertical plane of the window sash, and is incorporated in the side channel without increase in the width of the latter. It will be imderstood that the particular construction and arrangement of the parts housed within the side channel form no part of ie present invention, and other parts and arrangements maybe employed therein, as desired.

In the modified form of my invention illustrated in Figs. 9 and 10 the locking of the removable stop is eifected by meansof a screw 35supDOrted.

in a shouldered bushing 38 swedged or otherwise suitably securedinahole 31 inthe flange l8 of the, removablestop, disposed at a point wherethe screw may be screwed beneaththe upper shoulder of the slot2il of the flange 12 in the engaged posi tion of the removable stop to thereby secure the latter against retractive ordisengaging movement,

To disengage the removable stop the screw is with-.

drawn to a point where it is out of. the path of theflange i2 therebyjpermitting the stop to be moved longitudinally and the cross-pin 22 to be disengaged from the s lot 20. I

The side channel'according to my invention is very compact and narrow in width, providing a maximum clear vision through the window, is of lightweight, and provides a construction in which the removable stop may be readily and conveniently engaged and disengaged with the .fixed t p. i

I have illustrated and described a preferred and satisfactory embodimentof the invention, ;but it will be obvious that changes may be made therein, within the spirit and scope thereof, as defined .Having thus described my invention what I claim and desire to secure, by Letters Patent is:-.

fin a window construction, a side channel for receiving the edge of. a window sash, comprising a stop adapted to be fixed to a side post, said fixed.

stop comprising a side leg, a base, and a, flange projectingfrom said base in spaced relation to said leg, said flange having alongitudinal notch and a bayonet slotat one end of said notch, a re movable stop'comprising asidejleg and a flange in spaced and parallel relation to said side leg, a cross pin secured betwee'n said side leg and flange of said removable stop retaining said flange against outward distortion with respect to said side leg, adapted to be laterally engaged with said notch and engaged with said bayonet slot through longitudinal movement of isaidremovable stop, said leg being disposed at the inner side and said flange being disposed at the outer side of said flange of the fixed stop, toenclose and conceal said flange of the fixed stop:
